The magnetic application in the area of astronomy

　　From the magnetic products factory, we already know that the earth is a giant magnet, but where does its magnetic come from? Is it the ancient times? Is it related to the geological condition? How is the magnetic field in the universe?

　　At least, we have all seen the bright lights in the picture. Since ancient times in China, it had the records of the aurora borealis. Northern Lights are actually the result of the interaction of the particles in the solar wind and geomagnetic field. The solar wind is a high-energy stream of charged particles from the sun. When they reach the earth, interacting with the geomagnetic field, it is as if with a current conductor in a magnetic field force, making these particles the south Arctic sports and aggregation, and the rarefied gas of the Earth altitude collision, resulting in gas molecular excitation, and thus luminescence.
